AN ANALYTICAL SOLUTION FOR SINGLE PILE SUBJECTED TO TORSION

Torsional loading on piles are introduced due to eccentric horizontal forces on the supporting structures. Structures such as, tall buildings, bridge piers, offshore platforms and electric transmission towers, can be subjected to significant torsional loadings due to eccentric lateral forces respectively from high-speed vehicles, ship impacts, wave and wind actions, and other sources. Inadequate design of the piles against torsion may seriously affect the serviceability and safety of these structures with catastrophic consequences.The present work reported herein is aimed towards developing a rigorous analytical solution for single pile response subjected to torsion.
